What does 1 tick on whatsapp mean?

I texted my friend in an emergency and now I’m worried because, What does 1 tick on whatsapp mean when they seem active but never respond to me?

One gray tick indicates that your message has been sent on your phone and has not been received by that of the recipient. This occurs when their phone is switched off, when they do not have the internet or when they have limited you.

1 tick on WhatsApp means the message has been sent from your phone but not yet delivered to the recipient.

A single grey checkmark indicates that WhatsApp's server has successfully received your message after it was sent from your phone. But it hasn't reached the recipient's device yet, probably because their phone is off, they don't have an internet connection, or you might be blocked.
